Whenever we read the effective time managment strategies, we should remember that it is not practical to be done every day for an average person and some techniques would be cumbersome for a few of us. At least, this is what I have epxerienced so far. The human mind is like an untamed horse and many times a day, it just wanders. What I mean is efffective use of time is always hindered by disturbances and our lack of focus.
For me, the morning begins often at time. By lunch time a delay of upto an hour creeps up. At the end of the day, I would end up staying an hour or hour and half extra on at least 4 days a week. The error may be due to me or just the circumstances. Initially, I used to feel very bad but now, I don't pay too much heed to this unless, there is an important deadline to be met.
When we talk about time management, I think, we should also think along the lines of time we have to spent with family, time take to arrange important/legal documents in order, timely purchase,investments, insurance policies, health checks etc. When we are effective in the long term time management, our lives would be better.
